IMS Xpress leverages years of collective experience delivering field-proven, industry-leading solutions to the world's largest service providers. It is IMS standards compliant, and goes beyond technology integration to include joint business processes for product design, implementation and support.

"Service providers are looking to build revenue generating applications using the IMS architecture, but many IMS solutions have been too complicated and costly to operate," said Andy Ory, chief executive officer, Acme Packet. "Through our joint solution with BroadSoft®, IMS Xpress includes a fully-interoperable service that allows for rapid deployment of new services in a cost effective manner."

"For more than a decade, we have been singularly focused on enabling the delivery of modern communications services over IP networks, continuously innovating to ensure our service provider customers can offer the most demanded services, which increasingly include VoLTE, RCS and a broad range of Unified Communications services," said Michael Tessler, chief executive officer, BroadSoft. "Together with Acme Packet, we are enabling service providers to leverage the power of IMS without the costs and complexity of today's solutions."

Acme Packet and BroadSoft will host joint meetings at Mobile World Congress 2012 February 27-March 1 in Barcelona, Spain. Please contact the company representatives listed above for more information.
